In which direction does the frictional force act on the cube? A) upwards B) downwards C)in all the directions D) side to side

D) side to side

Explanation:

The frictional force act on the cube in the side to side direction. The friction force acts opposite to the direction of the motion of an object which reduces its speed or sometimes prevent it from moving from one place to another. In order to reduce the force of friction, the body has to move by rolling instead of sliding and use of lubrication on the surface on which the object moves.
